CONFECTION-COATING MACHINE.

Application filed October 31, 1922. Serial No. 598,220.

To all whom it may concern:

Be it known that I, ALONZO Lm'ron Bans- MAN, citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Confection-Coa ting Machines, of'which the following is a specification.

This invention relates to improvements in confectionery coating machines and is particularly concerned with the provision of improved means tending to prevent the formation of the disfiguring tails commonly formed on the coated confections during, their transfer from one conveyer to another.

Examples of prior machines having this object in view will be foundin U. S. Letters Patent No. 1,302,205, granted April 29, 1919 on an inventionof Antonio Pagliuca and in U. S. Letters Patent No. 1,341,253 granted May 25, 1920 to Alonzo Linton Bausman. others of which I am aware, attain their object by means which are located between the two conveyers and which eliminate the tail after its formation. They also require the addition of the tail removing mechanism as an adjunct to the machine and require a relatively large gap between the conveyers to receive the tail removing part of such mechamsm,

According to this invention, the desired result is accomplished by properly shaping that roll, which underlies the upper lap of the pervious coating machine conveyer at its delivery end, so that those portions of the conveyer supporting the confections are enabled to contact with the surface of this roll,this result being. hitherto prevented by connecting portions underlyin the first named portions and holding the %atter out of contact with the roll.

Wi'th the described arrangement those portions of the coatings, which drip from the" confection and depend throu h the pervious conveyer, are wiped off y, the specially formed roll leaving nothing to be subsequently drawn out during the transfer to the delivery conveyer to form a tail. In other words, the improvement tends to prevent the formation of a tail while the prior machines permitted the formation'of a tail and later removed it.

These machines, as well as all- According to a further feature of the invention the described roll is preferably driven at a surface speed greater than that of the pervious conveyer.

Other features and advantages will a war in the following description and in t e illustrative embodiment of the invention in the accompanying drawings, in which Fig. 1. is a plan view, with arts broken away, showing the delivery en of the pervious conveyer of a confectionery coating machine, embodying the invention;

Figs. 4 and 5 are small scale front and rear elevational views, respectively, of the coating machine, illustrative of the driving connections for the parts shown in Figs. 1 and 2; and

Fig. 6 1s a fragmentary cross-sectional view showing the invention applied to a.

different type of pervious belt.

Referring to these drawings: A. represents the casing of a confectionery coating machine, which may be of any suitable type and a full disclosure of one suitable t e will be found in U. S. Letters Patent 0. 7 90,184, granted May 16, 1905, on an invention of. Gabriel Carlson. The particular details of the coating machine may be varied, as desired, and the resent invention is concerned only with the act that the confctions, coated in any desired way, are carried. on a pervious oonveyer, such as 10, at a time when their coatings are still soft and workable and transferred to another conveyer, such as 11, which may be and is usually the delivery conveyer,--a non-pervious belt by which the coated confections are carried away to the cooling room.

The conveyer 10 may be variously constructed, as desired, but usually isin the nature of a wire screen, or interlaced wire fabric, which permits of excess coating dripping from the confections during their travel. One common way of constructing conveyor '10 is clearly illustrated in Figs. 1 and 2 in which a plurality of wires, each bent to provide alternate ofli'set parallel portions 12 and 13 connected by portions 14, are interlaced to form an endless pervioue conveyer or :wire :belt. The portions 12 and 13, ortransverse members of the con-' veyer, all lie in one common horizontal plane' and afiorda smooth, fiat, confection- 5 supportingsurface. The portions 14, forming the longitudinal members of the conveyer, do not project above the plane of the portions 12 and 13 and :are largelyxlocated therebelow as will be clear from Figs.

2 and 3. At least there areportions of the members 14 which extend below the transverse members '12 and 13 by distances equal 'to'flie dinmeterpf the WlI'GOf which these members are" formed and in all prior coat- 15 ing machines (utilizing so called wire belts) theportions 14, or'equivalent portions, contact" with the periphery "of the" supporting rolls 'for'the -Wire belt and hold the portions12'and 13, orconfection supporting "members," out "of contact with the rolls;

- Theaction, justdescribed,'is notparticmay material exce'pt atthe deliveryend ploy a'roll 15, which is grooved, as at 16, at

suitable axially spaced intervals to receive thelongitudinally disposediand under "ng portions 14' of the conveyer 10. hese grooves are of'snchdepth as to allow the transverse members 12 and 13 to lie flush and contact with the periphery of roll 15 andithis allows the roll to come into very close roximit to the bottom of aconfection', suclias c, and exert a wipingz'action to"either remove the-tails or rework them nnderthe bottoms of the-confections- In fact, the top surface of roll 15 will contact with the bottom of the confection when the conveyer is positioned, as in 3, and the dripping "d willliegradually wiped oil, o1"'worked into the bottom of the confectio'n; being entirely eliminated as'the rear.

endof "the confection moves out of contact with roll' 15. i The' conveyer 10 used in chocolate coatlng "machines, is sometimes made like that disclosed in U. S; Iietters Patent No. 1,009,- 670, 'anted Nov. 21, 1911 on an invention oFT eodor and David Kihlgren. Such a conveyor ismade up ofmembers interlaced in -the same-general fashion, as heretofore set'forth, e xcept'that the transverse members *a'r'e' o'ff substantially zigzag shape (Fig. 6) andliave inclined portions 17 andshoulders 18.

'The conveyers 10 and 11 may be supported-"and driven in any suitable manner and, as an illustrative example, the arrangement shown in 1 and "5 may be used for-driving the parts 'fr'o'm-the 'coa'tin'g-anav chine,'nf which 21 is the main driving shaft.

Asaconvenient practi cal way of obtaining-this result without any change in the standard drivingmechanism of the coating machine, the roll 15 is made larger in diameterthan the standard "roll which it replaces -such standard rollbeing ordinarily driveir by the-gearing described at the same surface speed as conveyer '10.

That is the wires 12 and 13, which move at a slower speed than the pcriphery of roll 15, furnish edges against which the drippings of the coating are carried by roll 15 and pinched off in a manner closely analogous to a scissors, or shearing action, which I believe materially improves the results accomplished.

The invention has been disclosed herein, in an embodiment at present preferred, for illustrative purposes but the sco e of the invention is defined by the appen ed claims rather than by the foregoing description.
